Subject: i210 performance ?

Hi All,
after porting Intel's Data Plan to QNX 6.5 I'm doing some performance
test with "testpmd".
I'm using a single i210 board installed on a dual core QNX 6.5 machine
and using "testpmd" as a packet generator (UDP packets).
The test are done with:
start: testpmd -c 3 -n -> interactive mode by default
set burst 1
set fwd txonly
start
stop
Without a delay between packets I see a huge number of dropped packets.
After introducing a delay of 60us after sending the "packet burst"
dropping of packets doesn't happen.
My questions are: why dropps the i210 packets ? Is it because of the
fact that probably all send descriptors are occupied ?
Best Regards
Armin Steinhoff
